This is a bright ink which pops on the page. Great for marking up documents, it really stands out. Very easy to clean. No fuss whatsoever. There is no shading that I can see. This ink is consistently in use and has been for about two years now.
Currently in my Karas Kustoms INK which has a needlepoint nib from Franklin-Christoph’s Masuyama tuned group.
It’s just lovely.
